A giant black hole 290 million light-years away destroyed a large star and threw its pieces into space. NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton scoured the wake of this event for information. The X-ray data reveals the relative amount of nitrogen compared to carbon in this stella
and strewn its contents into space. By analyzing the details of the X-ray data, the team were able to estimate the relative amount of nitrogen compared to carbon in the aftermath of this gravitational assault. These elements provide valuable clues to the researchers for what type of star met its demise.tidal disruption event

Astronomers have seen moderately massive stars like ASASSN-14li’s in the star cluster containing the supermassive black hole in the center of our galaxy.
